KARL BALLOD, OF RIGA, RUSSIA.-

CYCLE-LOCK.

T 0 all whom it may concern:

Be it known that I, KARL BALLOD, a subject of the Czar of Russia,residing at Ri'ga, Russia, have invented certain new and usefulImprovements in Cycle-Locks, of which the following is a specification;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable othels skilled in theart to which it appertains to make and use the same.

This invention relates to a lock for cycles in which a lever engagingbetween the wheel spokes prevents forward movement of the eye e.

The lock serving to hold the lever between the wheel spokes consists ofa part fixedly mounted in the lock casing and a part swinging againstthis which on the one hand carries the locking latch and in the swingingmovement draws this back into the closed position. The swinging partconsists of two plates firmly connected with an open intermediate space,on the outside of which plates is or are resiliently pivot-ed one ormore levers with their ends bent to hook shape which levers project intothe said intermediate space so that a key inserted through a slot in thelock casing the fiat edge of which is stepped to correspond to thenumber of projections by applying it against the same causes the leversso called tumblers outside the plates to swing out; thus the hook shapedends of the tumbleis are brought into such a position that as soon asthe key receives a pressing movement they can engage in longitudinalslots in the part firmly connected to the easing whereby it is madepossible for the movable part consisting of the two plates to make aswinging movement under the action of the key. By this swingin movementthe boit firmly connected with the two plates is drawn out of the lockedposition. The lock is held in the open position by a lever resilientlymounted on the swinging part being held by a nose against a projectionon the lock casing. If now the lever passing through the wheel spokes isbrought into the locked position it engages in a notch in the lock casmgin such a manner that it raises the lever holding the look in openposition so that the swinging part consisting of the two plates inconsequence of spring actuation swings into the locked position. In thismanner the bolt carried by the swinging part engages thepartSpecification 01' Letters Patent.

of the locking lever engaging in the lock casing and holds the samefast.

The invention is illustrated by way of example in the accompanyingdrawing in which Figure 1 is a view of the lock (with the cover removed)in the locked position. Fig. 2 is a view of the lock in the openposition the casing being shown in longitudinal section and the keybeing shown insert-ed. Fig. 3 is a section on the line AB of Fig. 1shown in the direction of the arrow. v Fig. 4 shows the arrangement inthe locked position of the lock in connection with the lever locking thewheel seen below.

The casing a has on one longitudinal side a slot b for the introductionof a key e while on one broad side another slot d is provided by whichthe locking leverf swung through the spokes of the wheel against theaction of a spring 0 engages in the interior of the casing; the lever ispreferably provided near its outer end with a notch f. The slot (1extends through the upper and lower cover of the casing.

Rigidly connected with the latter is a U- shaped partg, about a bolt gmounted transversely thereof is pivoted the swinging part of the lockconsisting essentially of two plates h and t. On the bolt g is furtherarranged a spring 9" actuating the swinging part It, i. The two platesh, i are united at their upper edge so as to form a unitary structure,as well as at their lower part in an extension piece I: which is formedas a bolt.

On the outside of each of the plates h and i. are pivoted one or morespring actuated tumblers Z the upper ends l of which are bent inwardsafter the manner of a hook while projections 1" carried by the sameproject through the slot in the plates 71-, i into the intermediatespace inclosed by the latter. The arrangement of the projections on thetumblers Z is such that the latter are arranged in stages so that whenthe key 0 is introduced through the slot b of the casing a into the openintermediate space betueen the two plates h and i the stepped wards ofthis key 0 come againstthese projections Z".

Small holes are provided in the plates 7:. and 1' through which pass theends of the springs a bringing the levers Zback into their originalposition.

A trigger o firmly connected with the two plates hand i hasjor itsobject to serve along' with a pro'ection as a support for the outer endof the 'ey c in order to limit the inward movement of the same and totransmit the swinging movement of the'key on to the swinging part of thelock.

By means of a pin below the bolt is is pivoted a spring actuated lever pthe front end of which is provided with a nose p.

The U-shaped part 9 firmly connected with the casing has on each of itstwo limbs longitudinal slots g in which the hook shaped ends 1 of thetumblers may engage on introducing the key a into the lock.

The action of the arrangement is as follows: In the position ready foruse shown in Fig. 2 the swinging part it, i is swung downwards so thatthe bolt 7:: does not project into the slot'd in the casing; thetumblers Z engage with their hook shaped ends Z in the slots q of theU-shaped fixed part g. The lever p bears with its nose 1) against theedge of a check of the casing limiting the slot d. If new the lockinglever f is swung through the spokes of the wheel and introduced into theslot d in the lock casing it comes against the lever p and presses thesame downwards against the action of a spring; by this the swinging parth, i, loses its sup port and swings under the action of the spring '9into the position shown in Fig. 1. The bolt k hereupon engages in thenotch f of the locking lever f and prevents automatically the return ofthe same. The levers 1 have left the slots g with their hook shaped endsI and swing under the action of their respective springs in such mannerthat the hook shaped ends Z do not lie above the slots 9. Any attempt tomove the movable part It, i downwards by artificial means would then befrustrated as the hook shaped ends Z lie on the upper edges of the limbsof the U- shaped part 9. If the lock is to be opened then the key 0 isinserted through the slot 1) of the casing and is pressed in such mannerthat the wards of the key carry with them the rojections Z of thetumblers Zso that the heel: shaped ends I of the latter come into aposition above the slots g whereupon a swingmg movement is imparted tothe key 0 (see posit-ion of Fig. 2) by means of which the art h, 'i iscaused to swing the hook shaped ever and the ends Z enter the slots (1and the bolt It leaves the slot (1; simultaneously the lever under theaction of its spring bears with t 1e nose p against the lug on thecasing and so secures the swung out part 7, i in the position shown inFig. 2. The locking lever flcan now be directly withdrawn from the s ot.

The whole arrangement is so mounted on the fork, that when locked it isnot removable For this purpose the clips t and t are fixed on the barsa: of the fork and then the arts I and II with their bolts are screwedinto the clips 1' and r. The nuts 8 and 8 serve only to tighten theclips. In such an arrangement the lock cannot be removed when in lockedpo'sition.
